Additional Notes

  • The dry fill capacity for the Mazda MX-5 / Miata NA 1.6 (EU) automatic transmission stands at 6.7 liters, a figure that reflects the total fluid volume required when filling a completely drained or rebuilt unit where the torque converter and all internal passages are empty.
  • The service fill capacity is rated at 4.2 liters for the 1990-1993 1.6 automatic transmission, representing the amount of fluid displaced during a routine drain and refill where residual fluid remains in the torque converter.
  • The difference between the 6.7-liter dry fill and the 4.2-liter service fill — a gap of 2.5 liters — reflects how much fluid is retained in the torque converter and valve body during a standard service, which is a common characteristic of automatic transmissions serviced without a full flush.
  • Under normal use conditions, the 1990-1993 1.6 automatic transmission is subject to a check interval of every 10,000 km or every 6 months, whichever comes first, with both a mileage and a time-based threshold applying simultaneously.
